Mine mastery allocates to speed key when zoning

Every time I zone my middle mouse click resets to passive Mine Mastery-"detonate mines are triggered when you are moving". This skill is passive and triggers automatically. I put a skill there so I can middle mouse click to set it off but again when I zone the stupid skill that is automatic and I don't need to trigger automatically appears in middle click spot. So I have to reset to the active skill. I have unallocated and reallocated. I have tried switching mouse button in options. Still keeps allocating itself when I
Can anyone help?

confirmed here. Allocating the mine mastery immediately switches whatever spell you have on middle mouse button to "detonate mine", grayed and with the "triggered so you can't use directly" info.

With the painful loss of left mouse options, losing one more hotkey makes gameplay... difficult. Please correct this.

it's working, thanks for the fix GGG
